Resistance: 0.2 - 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump and/
or the lead wire.
(g) Inspect the fuel pump operation.
Connect the battery positive (+) lead to terminal 4 of the
connector, and the battery negative (-) lead to terminal 5.
Check that the fuel pump operates.
NOTICE:
These tests must be done quickly (within 10 seconds)
to prevent the coil burning out.
Keep the fuel pump as far away from the battery as
possible.
Always change the connection on the battery side.
If operation is not as specified, replace the fuel pump and/or
lead wire.
(h) Reconnect the fuel pump & sender gauge connector.
(i) Reinstall the rear floor service hole cover with the 2
screws.
(j) Reinstall the front and rear floor carpets.
(k) Remove the 2 rear door scuff plates, the step plates and

REMOVAL
CAUTION:
Do not smoke or work near an open frame when working
the fuel pump.
1. REMOVE NO.1 REAR SEATS
2. REMOVE REAR DOOR SCUFF PLATES, STEP
PLATES AND REAR SEAT LOCK COVERS
3. REMOVE REAR FLOOR SERVICE HOLE COVER
(a) Take off the front and rear floor carpets.
(b) Remove the 2 screws and rear floor service hole cover.
4. DISCONNECT FUEL PUMP & SENDER GAUGE CON-
NECTOR
5. DISCONNECT FUEL MAIN TUBE AND RETURN TUBE
(FUEL TUBE CONNECTORS) FROM FUEL SUCTION
PLATE
CAUTION:
Perform disconnecting operation of the fuel tube con-
nector (quick type) after reading the precautions.
(See page SF-1)
Prevent the retained pressure in the fuel line from
splashing inside the vehicle compartment.
Be careful not to damage the contact surface or let the
foreign matters on there when sealing the tube and
the suction plates with the quick connectors through
O-ring.
Be sure to perform the disconnection by hand. Do not
use tools.
Do not bend or turn the nylon tube by force.
(a) Before the operation, remove foreign matters or dirt stick-
ing to the tube joint clips.
(b) Enlarge the tip of the clips with fingers and pull them out
for disconnection.
(c) Pull out the fuel main tube and the return tube.
If the nylon tube and the suction plate stick together, ease the
connection by turning the nylon tube with fingers and pull it out
for disconnection.
NOTICE:
Plug the port of the fuel suction plate with a clean rubber
cap.
(d) After the disconnection, protect the connector with a plas-
tic bag.

Be careful that the arm of the sender gauge should
not bent.
(c) Remove the gasket from the fuel section plate.
7. REMOVE LEAD WIRE FROM FUEL PUMP
8. REMOVE FUEL PUMP FROM FUEL PUMP BRACKET
(a) Pull out the lower side of the fuel pump from the pump
bracket.
(b) Disconnect the fuel hose from the fuel pump, and remove
the fuel pump.
(c) Remove the rubber cushion from the fuel pump.
9. REMOVE FUEL PUMP FILTER FROM FUEL PUMP
(a) Using a small screwdriver, remove the clip.
(b) Pull out the pump filter.

INSPECTION
1. INSPECT HEATER RESISTANCE OF HEATED OXY-
GEN SENSORS
(a) Disconnect the oxygen sensor connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal +B and HT.
Resistance: 11 - 16 W at 20°C (68°F)
If the resistance is not as specified, replace the sensor.
Torque:
44 N´m (450 kgf´cm, 32 ft´lbf) for sensor 1
20 N´m (200 kgf´cm, 14 ft´lbf) for sensor 2
(c) Reconnect the oxygen sensor connector.
